ABSTRACT:
An improved side opening pneumatic carrier is used in a remote transaction pneumatic tube delivery system. A pair of symmetrical semicylindrical shells are provided with interior end pieces on one end and exterior end pieces on the opposite end. Hinges are formed along one longitudinal edge of each of the semicylindrical shells for joining the shells and forming a generally cylindrical carrier in the closed position. The external end piece on each end of the shells is dimensioned to closely engage the interior walls of the pneumatic tubes, so that the carrier cannot be inserted into the system unless it is completely closed. A lever attached to each of the internal end pieces is fitted within an opening of the opposite external end piece and biased by a spring assembly to maintain the semicylindrical shells in a normally closed position. The carrier is opened by rotating each of the external end pieces in opposing directions, thereby providing easy access to the contents of the carrier and preventing the carrier from being opened when it is within the pneumatic tube delivery system.
